BTW I have been trying to find a country where an exchange can be hosted that does not cow to fincen
Basically no such country exists, not any more. Singapore and Hong Kong were the last holdouts I knew of and they're towing the line now too.
Andorra, Monaco, wherever.
Start with countries off-sides from the U.S. which aren't under international sanctions. Iran, Venezuela, Cuba, UAE, Uruguay, Fiji, Seychelles, Madagascar, Mozambique, Zimbabwe, Laos, Myanmar....
